Adam's Height

Basically, the Hadith was mistranselated and Adam was 60 cubitis in Heaven not on Earth as I first mentioned before.

Imam Bukhari narrates in his Sahih;

Narrated Abu Huraira:

The Prophet said, "Allah created Adam, making him 60 cubits tall. When
He created him, He said to him, "Go and greet that group of angels, and
listen to their reply, for it will be your greeting (salutation) and
the greeting (salutations of your offspring." So, Adam said (to the
angels), As-Salamu Alaikum (i.e. Peace be upon you). The angels
said, "As-salamu Alaika wa Rahmatu-l-lahi" (i.e. Peace and Allah's
Mercy be upon you). Thus the angels added to Adam's salutation the
expression, 'Wa Rahmatu-l-lahi,' Any person who will enter Paradise
will resemble Adam (in appearance and figure). People have been
decreasing in stature since Adam's creation. (Volume 4, Book 55, Number 543)

Many orientalists and the Shia have been very critcal of this narration in Bukhari and they also question the authenticity of the hadiths narrated in Bukhari because of such hadiths.

Not to mention Muhsin Khan translations are absolutely horrifying
in their travesties of the English language.

Many people fail to understand that the Prophet (Peace and Blessings be Upon Him) did not speak English. Nor do these people bother to read the original arabic of the hadith.

If we examine the hadith in its original Arabic we find,

"khalaqa-llaahu aadama wa Tooluhu sittoona thiraa`a.."

This means "Allah made Adam, and his height was 60 cubits.."

This is talking about the height of human beings in Paradise and not
in the world.

"So everyone who enters Paradise (will be) upon the likeness of Adam,
for they have not ceased from being decreased in stature even until
now."

When Adam (Peace be Upon Him) fell from grace he was given a worldly decrease in stature which mankind is still upon to this day. When we enter Paradise again we return to that heavenly stature (inshaa' Allah).

This is supported by another hadith in Bukhari,

Narrated Abu Hurayrah:

Allah's Messenger said, "The first group of people who will enter
Paradise will resemble the moon in the night of its fullness...All of
them will be upon a single semblance, upon the resemblance of their
father Adam, 60 cubits (tall) in the sky." (Sahih al-Bukhari 4:544)

So that there is no room for doubt, the Arabic for "...upon the
resemblance of their father Adam, 60 cubits (tall) into the sky" is
"`alaa khalqi rajul waaHid, `alaa Soorati abeehim aadama sittoona thiraa`a fis-samaa'"

As we can all see now the reference to "60 cubits tall" is in
reference to ALL mankind when they are in Paradise.
